WOVEN PILE FABRIC.

SPECIFICATION forming part of Letters Patent No.484,541, dated October18, 1892.

Application filed November 13, 1890. Serial No. 371,289. (Specimens.)

T0 all whom it may concern/.-

Be it known that I, FRED PEARsoN, of the city of Philadelphia, and Stateof Pennsylvanla, have invented a certain new and useful Improvement inWoven Pile Fabrics; and I do hereby declare the following to be a full,clear, and exact description thereof, reference being had to theaccompanying drawings, forming part of this specification.

My invention has relation to double pile fabrics, and particularly toplain plnshes; and it consists in the weave and construction,hereinafter particularly described.

The object of my invention is to provide, in a novel weave, aconstruction materially different froIn any heretofore invented by me orby others, a plain double pile fabric having an even surface presenting`the appearance of one even mass of pile without' pile marks or ridgesappearing across the goods.

A further object is to provide at the same time a substantial fabric soconstructed as to prevent the pile from ypushing out through the back,and also to prevent the pile from losing its approximate Verticalposition and the vthreads from becoming crossed or matted.

I do not herein claim Vor seek to cover, broadly, the idea of arranging,in connection with ground Warp-threads and ground weftthreads and withtufts of pile engaged with picks of said ground weft-thread, a secondset of weft-threads the picks of which are im mediately behind the picksof ground-weft with which the tufts of pile are engaged and a second setof warp-threads which bind said second set of weft-threads to the groundweftthreads, as such broad idea or invention is embodied and claimed inan application filed by me in United States Patent Oliice-ongthe 31stday of March, 1891, Serial No. 387,114.

In my improved weave herein described I preferably employ four binder orwarp threads and one pile-thread in one reed-space in weaving doublepile fabrics. Each pile-thread appears as in pairs in each fabric, eachpilethread of a pair formed, respectively, on opposite sides of thesaine pick and on every other pick in a series, apick interveningbetween each pair of pile threads thus formed in the same line. Awarp-thread is arranged 011 the face of the fabric, preferably from thesaine reed-space on each side of the said pilethread, similarly shedwith relation to the weft, one warp-thread passing through the entirefabric and the other through the upper or face series only ofv thepicks. An additional pick is formed back of each pilethread, thussecuring it between two picks, which picks are bound together by seriesof Warp or binder threads, preferably two in number, formed alternatelyover and under the two series of picks or weft-threads, thus forming ineach fabric an additional or auX- iliary backing.

In the accompanying drawings similar letters of reference refer tosimilar parts throughout.

Figure l is a sectional View of the double pile fabric before the pileis cut, as on the line am; of Fig. 2. Line w w indicates the line ofseverance of the pile-threads in dividing the fabrics. Fig. 2 is apartially-sectional plan vieW on the liney y of Fig. l. Fig. 3represents a bottom View of the fabric. Fig. lis a sectional view of thefabric on the line z .e of Fig. l.

A represents one series of binding or warp threads, and A thecorresponding binding or Warp thread between which the pile-thread ct isinterwoven with the picks j). B B are also binding or warp threads,between which the pile-thread b is interwoven,also,with the picks p.Said warps A A and pile-thread a are formed in a separate reed-spacefrom the warps B B and the pile-thread b. The said Warps A B areinterwoven with the first or upper series of picks 1J.

Back or underneath the first series of picks p is formed an additionalauxiliary series of picks p', between which two series the pilethreadsaandbare bound. The warpsAand B form the binder Warps orthreads of theupper or lirst series, the picks passing over and under every pickalternately up and down and bind the said picks p together, While theWarps A and B form the binder warps or threads for the two series ofpicks p p', passing over and under said two series of picks p palternately up and down, and bind the two series of picks and the wholefabric together. hile the two series of warps A A are formed in the samereed-space, the warp A does not IOO pass through the entire fabric, butonly over and under the Iirst or upper series of picks p, while the warpA passes through the whole fabric over and under the two series of picksp p alternately, the same process occurring with the warps B B',respectively, in a separate reed-space. Between the warp A and B nopile-threads are preferably employed.

A number of weft-threads may be thrown with each shot of the shuttle,forming a single pick instead of a single weft-thread. The pile-threadsa and Z) are thus bound and secured firmly in the fabric, having in thelength of the goods on each side of each pilethread a separate warp andon the remaining sides a separate pick, thus binding the pilethread rmlyon four sides into the fabric and preventing any lateral displacement,while on the back of each pile-thread is formed the additional orauxiliary backing, which prevents the pile being forced out through thebacking. The picks on which the tufts of pile are formed are preferablythose of the face or upper series which are depressed by the warpspassing over the outer surface or face of the pick, which thus bindsthetuftformed onthe said picktightlybetween the said upper pick and thepick of the fabric formed immediately underneath the saine. It

will be clearly seen that the pile-threads are thus bound rmly into thefabric and prevented from being pushed out orlosing their proximatevertical position, and in the arrangement and construction described theridges or pile-marks common in plush fabrics are also thus obviated anddone away with, and the pile surface presents when the double fabricsare cut apart a snioothand even appearance.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

1. The herein-described pile-fabric, having two sets of picks, one setformed underneath the other and bound together by binderthreads, andtufts of pile formed in pairs and in series between two parallelwarp-threads on each side of every alternate pick of the face series ofpicks and caught between-the upper and under series of picks, theproximate series formed on alternate picks from that of the next series,substantially as described.

2. A pile fabric having a double set of picks, one set formed back ofthe other and bound together by alternate binding-warps, the upperseries bound, also, together by separate binding-warps, and tufts ofpile bound and secured between the said two sets of picks, each tuft ofpile formed on alternate picks of the face series of picks in series andeach tuft bound between two warps, one on one side passing through theentire fabric and the other on the other side passing through the upperseries of picks only, substantially as described.
